This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Potassium and Cultivar Effects on Carbohydrate Partitioning in Upland Cotton written by and published by . This book was released on 2006 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indeterminate growth habit of upland cotton (Gossypium hirsutum L.) reduces the efficiency of yield formation when grown as an annual for its lint. Altering the determinacy may provide greater carbohydrate partitioning to reproductive structures, allowing higher yields. Another factor that may influence partitioning is potassium (K) nutrition. Potassium is essential for physiological and biochemical processes including translocation. It is necessary for ATP production, which is crucial for phloem loading and unloading. A three-year experiment was conducted at the West Tennessee Research and Education Center to evaluate carbohydrate partitioning in Paymaster 1218BG/RR (PM1218), a relatively determinate cultivar, and Deltapine 555BG/RR (DP555), a more indeterminate variety. The two cultivars were grown in the field under two levels of potassium fertilization, 60 and 120 lbs K2O/acre/year, representing adequate and excessive K fertility, respectively. Plots containing cultivars and K treatments were arranged in randomized complete blocks with six replications per year. Plant samples were harvested at early bloom and after cutout, to evaluate partitioning during boll filling. Eight stem samples per plot were collected immediately below the cotyledonary node, freeze dried and ground for carbohydrate analysis by enzymatic methods. The two sampling dates were treated as subplots in the statistical analysis. Plots were mechanically harvested and samples of seedcotton were ginned to determine lint yields. Results showed that K had significant effects on monosaccharide concentrations of both cultivars and on lint yields of PM1218. Lint yields of PM1218 were lower than DP555 with 60 lb K2O/ac/yr, but were equivalent at 120 lb K2O/ac/yr. Total soluble sugar concentrations were higher in DP555 than in PM1218 at early bloom but declined to equivalent concentrations after cutout. Starch analysis revealed both a cultivar and harvest sample date interaction. In all years, PM1218 had more starch than DP555 at early bloom. Accumulation or depletion of starch reserves during boll filling differed by year, along with lint yields. Relating these results to shoot biomass data, also collected at both harvest dates for another study, confirms that the determinate variety PM1218 allotted more photoassimilates for reproductive growth during this time than DP555, despite similar lint yields. Previous research has found decreased vegetative growth during reproductive development in more determinate cultivars. Lower lint yields in PM1218 at 60 lbs K2O/ac/yr could be due to soil nutrient uptake efficiency and may explain the need for additional potassium in the more determinate cultivar. The two cultivars differed in carbohydrate concentrations at early bloom but by cutout were similar. Further investigation into the components of carbohydrate sink strength, such as seed constituents and root growth, may help in determining the carbohydrate partitioning trends of cultivars. Additional research is needed to establish potassium fertilization for optimum reproductive partitioning in determinate cultivars.

Download or read book Crop Physiology Case Histories for Major Crops written by Victor Sadras and published by Academic Press. This book was released on 2020-12-05 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops

Available in PDF, EPUB and Kindle. Book excerpt: Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.
